Revoltech Amazing Yamaguchi Black Flash presents a sinister, sleek silhouette built around a compact 170mm body. The figure sports a dark, form-fitting suit accented by glossy panels and sharp armor-like lines, capturing the menace of the Black Flash. Daichi F. Sugimoto's sculpting emphasizes motion-ready anatomy with pronounced shoulder, chest, and leg details that read clearly in dynamic poses. The set bundles a rich array of exchangeable parts: an additional head, eight hands, numerous energy and lightning pieces, a chest piece with lightning, two ear modules, an extra effect, and a display stand. The joint system allows dramatic sprinting, leaping, and impact poses while retaining stability.

Black Flash is the terrifying avatar of the Speed Force in DC Comics, a being who appears whenever a speedster faces fatal consequences in the wake of acceleration. Born of the Speed Force's darker side, the Black Flash embodies inevitability and consequence, swiftly pursuing those who outrun death itself. In various storylines, he arrives as a shadowy, death-bringing figure, often seen circling the fringes of the fastest heroes' battles before delivering a fatal blow or marking a turning point. This figure captures that aura—ephemeral, lethal, and relentless—while hinting at the mystery of the Speed Force that created him.
